The invention relates to lubricators for railway axle journals andcomprises a device for 27 Claims. (Cl.308-84) bearing 2, wedge 3 and box4 are of usual conpumping lubricant from a sump below thejournal anddistributing it to the face of the journal, the pump being operated bythe play of the journal crosswise of the box mounted on the journal asis characteristic in railway rollingstock.

More particularly the invention preferably consists in a pumping anddistributing assembly and asupporting and holding assembly, all adaptedto be inserted as a unit through the usual opening in the outer end of ajournal boxof American Assocation of Railroads general construction toposition the pumpingand distributing assembly beneath the journaljthesupporting and holding assembly being readily positioned and secured inplace by partsyieldingly thrusting against spaced portions of the boxand journal. i

The principalobjects of the invention are to construct a lubricator ofthe type described which is readily applied to and removed from a journal box and journal bearing assembly and" may be accurately positionedirrespective of manufacturing variations in the length, width, or depthof the box without any preliminary adjustments and without requiringpermanent additions to the box or any machining of the box for thepurpose of applying the lubricator.

Other detail objects of the invention will be apparent fromconsideration of the-present disclosure including the accompanyingdrawings 'in which- Figure 1 is a longitudinal vertical section throughthe journal of a railway axle andan A. A. R. journal box mounted thereonby means of the, usual bearing and wedge.

struction. The lubricator includes a pump 5, a pump operating device 6,a lubricant distributor I, supporting legs 8 and 9, and a'positioningstrut including elements In, H, [2, and I3. Legs 8 and 9 are pivoted attheir upper ends to distributor l and diverge downwardly and engage thetransverselycurved bottom wall M of the journal box (Figures 3, 4) whichcurves forwardly and upwardly at l6 (Figure 1) and is not there engagedby leg 9. Leg 8 also contacts the box rear wall l5. The strut l8, ll,52, I3: is pivoted to the outer end of leg 9 and extends upwardlytherefrom. Element l l telescopingly receives element l2, which isthrust upwardly by springs ll. Terminals l8 at the upper end of element12 are recessed to better engage the downwardly facing V rib 19 on thejournal box top wall 262 to anchor the lubricator in position. Thedownward thrust box shown in Figure lbutshowing the lubricator 1 as itisbeing 'applied or removed from the box.

, 1 Figure 9 is a perspective illustrating a journal," journal box,bearing, wedge, and lubricator as of springs I! urges elements ll; l3,L9, 7, and 8 downwardly and inwardly until the outer end of leg 3engages a box rear wall 15, whereupon continued thrust urges the ends oflegs 8 and 9 nearest each other, and distributor 1, upwardly so that thedistributor contacts the journal. 3

Preferably the distributor comprises a part 22 of fibrous material suchas felt, rope, or woven yarn, sewed or otherwiseattached to a backingsheet 23 of waterproof fabrics, such as canvas. This part is carried onthree flexible sheet metal strips 24,25, and 26, each extending fromside to side of part 22 and spaced from the adjacent strip or stripslongitudinally of the distributor.

Bars 21, 28, and 29 are arranged end to end near each side of thedistributor and they are pivoted to each other as indicated at 30 tocooperate with position. Supports 8 and 9 are pivoted to bars 21 and 29at 3| and 32, respectively.

Pivoted on cross bar 33 of support 9 is an wardly extendingcarriers-land positionedbetweenthe inner end ofzthis carrier anddistributor 22 is pump 5, comprising one or more collapsible chamberswith return check valve inlets 35anoutlets 36, there beingsprings 3'1,'38, 39

urging the pump chambers to expanded position. Pivoted on crossbar ii]of support e is a lever having an upstanding arm 4|, with a terminaldisposed to engage the outer face of the journal. The lever has arelatively short arm 42, the outer end of which contacts the undersideof carrier 34.

When journal I moves to the left from the position shown, lever M, 42 isrotated in an antisupports 6| and =62 ota'lly connected to each :otherand to the central 3 clockwise direction, lifting carrier 34 andcollapsing pump 5 to force fluid in the pump through valves 36 and tothe distributor. When journal I moves in the opposite direction, springs31, 38, 39 move the pump parts, carirer 34 and lever 4|, 42 to theposition shown, or to a more extreme position, fclos'ing valves 36 anddrawing fluid into the pump through valves 35. Continued operation ofthe lubricator in this manner maintains a supply of lubricant from thebottom of the box to the journal; The construction and operation of thepump itself are disclosed and claimed in more detail in applicationsfiled December 1,1194? now Patent No. 2,639,200, issued May :19, 1953.,and February 15, 1950, Serial No. 144,283, abandoned in view of acontinuation application filed August 14, 1952, Serial 'No. 304,277.

Preferably the lubricator includes structure for closing ofi the spacebetween the lower half of the journal and the edge of the opening therefor in wall I5 which forms the inner wall of the usual oil and dustguard pocket 43-, This structure is mounted upon k support 8 andcomprises two arcuate strips of felt-like packing ma: terial ,44, 45,respectively, strip 44 being pressed against box rear wall I5 and asimilar strip -45 being pre sed against the arcuate fillet between theaxle body and the inner end oi journal I. strip 44 is mounted -on abacking plate lfi which is supported by spring pressed plunger-s4I;slidable in uprights 48 pivoted at 49 to arms 50 on support 8.Elements 44, 46 ;are thrust in -a clockwise direction by aspring 5 lanchored to support 8 "wtih its intermediate portion looped and slidablyreceived in clips 52 on plate 46. A sheet of leather-lilce material 53extends upwardly from the upper edge of plate It and mounts strip 45. Aspring device 54, similar to spring 5 l,--is carriedby plate 46 andthrusts the upperportion of sheet 53 and {strip 45 against the journalfillet.

This sealing structure aceom-modates the-movement=of the journal backand forth in the box and provides for the contact of thetel-t stripswith the box rear wall and journal fillet, irrespective of variationsillXbhQ length of the box or the dis- 'tance between the bottom'of thejournal and the 1 13 11 wall. The sealing structureis automaticallyositioned by the insertion of the remainder of the lubricator intothe-box, and without requiring the opertaor to thrust his hands 'or atool to the inner endoi the box to adjust the seal. 7

In Figures '7 and a the jou l, e ring, wedg 'box, distributor, and,pump, are substantially the same "as the corresponding parts describedabove.

The supporting and holding assembly di-fiers from that.previously'described in several respects.

have their :upper ends pivsection 63 of the distributor "by 'asingle-pin 64. Support BI is substantially the same as support 8, butsomewhat longer: and is not. shown with-the seal for the spacebetwe'enthe journal and the edge of the oil and dust guard pocket,although such sealing structure 'asyshown-in Figures ,1 and 4 couldbemounted upon support 6i if, desired.

Support-B52 corresponds to support S-but-is-substantially longer and itsouter end is, pivoted =at fiidirectly to the telescoping unit-comprisingan a H frame with legs .66 and across bar :61. Legs 66 are tubular at 68to receive plungers G 9 surrounded by springs anchors H.

Preferably rollers j 12 are journaled on leg -62 and are positioned toengage the box walllfla- 4 I641, and facilitate the inward movement ofthe structure to the assembled position shown in Figure '7. The squareangle between the periphery and the outer face of each roller causes theroller to resist rotation of the distributor as a whole about thejournal axis as might be induced by the friction between the journal andthe distributor when the anxle is beginning to rotate and the journalhas not been lubricated, particularly in cold weather.

7 The pump operating deviec comprises a single rigid lever pivotedintermediate its ends on a cross member; 8 of support 62 and having anup- -standingarml3 a terminal 14 for engagement with theend of thejournal and having an inwardly extending horizontal arm supporting thelower portion of the collapsible pump 16 which corresponds generally tothe pump shown in Figures 1 and 2.

Support 52 functions as a lever fulcruming at its rollers '72 on theadjacent surface of the journal box with its outer end thrust downwardlyby spring 10 and its inner end thrust upwardly against the distributorll. Wi'th'this construction the distributor T1 is applied to the journalby thrust exerted along a central "transverse line and readily pivots onpin to contact the journal throughout the length of the distributor.

This construction has fewer parts and .is simpler than that shown .mFigures 1-"6 but "cin- -bodies 'most of the essential'elements of thelubricator.

Figure '9 illustrates a structure corresponding generally :to that shownin the above-described figures but differing in the following respects.

The right hand supporting and position unit comprises a central member'80 extending downwardly and inwardly from the distributor andterminating in an arcuate cross member 81 seated in the corner iormeclby'th'e boxbottom'wall Nb and rear wall 15b. The left hand supportingand positioning unit comprises pairs of two interconnected parts 3&2,3-3 hinged together by pins 84 in brackets 85, each having a dependinglug 86 engaging the box bottom wall and preferably for-med of hardenedsteel so that its edges will dig into the box wall and more effectivelyresist rotation of the lubricator with the journal. A telescopingyielding strut 8-1 with anchors 88, corresponding to. those previouslydescribed, is pivotally connectedto the outer ends of parts 83 andthrusts the'later downwardly from its seats on the box top wall 20b andagainst the box wall.

' tor rearwardly and upwardly and position the T0 and'car-rying terminaldistributor and pump lengthwise of the box, irrespectiveof substantialvariation in box lengths as is found in such gboxes which 'are made :bydifferent manufacturers and to varying degrees of accuracy.

The carrier 89 of the pump operating mecha- -nism is :pivoted at-90 tobrackets and includes,

a tail piece 31 terminating in -a cup 92 which seats springs 93, theupper ends of which bear against the :lower face 'of the iplate-likeoperating lever 94 which is provided with transversely spaced contactsthat its upper end for engaging the end of the journal... 7 a? Theflexible wall pump body 96 is normally ex tended by a single interiorspring. pump comprises a single chamber with one or more inlet valves'atits lowerhand end and outlet valves, at its upper endlea'ding "to thedistributor. 'The distributor comprises a single bottom plate 91 and asheet 98 of woven fibrous material for application to the journal. Plate9! possesses 'suflicient flexibility to be curved as required to passbetween the end of the journal and the edge of the opening in the boxend wall during insertion and removal of the lubricator into and fromoperating position.

A torsion spring I02, coils about the pivot I03 through which thesupports are connected to the distributor and has its ends seatedagainst the distributor and the right hand support and positioning arm80 and thrusts arm 80 downwardly to insure its contacting with thebottom of the box when the lubricator is installed.

A guard I04 is pivoted to the right hand end of carrier 89 and is loopedaround arm 80 and serves as a guard to avoid the lower edge E of thejournal box opening from being received between arms 80 and 89 andcatching the side of the pump body and injuring the same, or otherwiseinterfering with the installation of the lubricator.

Eccentric buttons I I15, threaded onto carrier 89, when in one angularposition, overlie the laterally projecting bottom plate of the pump andhold it to the carrier. When pins I05 are rotated 180, the pump may bereleased from the the carrier 89. If, at the same time, pivot pin I03 iswithdrawn, the distributor and pump unit may be removed from theremainder of the lubricator structure. This is an advantageous feature,permitting the ready replacement of worn pump and distributor parts.

It will be understood that the seal shown in Figures 1 and 4 may bemounted on the cross member 8|, if this feature is desired.

Each form of the invention comprises a single unit including thedistributor, pump, supports and, if desired, the seal for the opening inthe box rear wall, all readily inserted, through the usual opening inthe front of the box, into functioning position and just as readilyremoved by detaching anchors I8, II, or 80 from the position of the boxthey engage and swinging the adjacent framing outwardly of the box andthen swinging the remaining portions upon their interconnected pivots,compressing the pump and flexing the distributor as required to movethese parts outwardly between the journal collar and the upwardly andforwardly curved end wall of the box. Obviously features of theinvention may be embodied in less than the more complete groupsillustrated. A substantially smaller distributor and a difi'erent typeof pump could be used inplace of those shown, or one of these elementscould be omitted, without departing from the general principle of theinvention involving the positioning of a lubricator device in the box bymeans of a series of pivoted membersheld in functioningposition by theyielding thrust against oppositely facing surfaces of the box assembly.4 i
